What do you pack for a weekend tour?

I am bringing everything with me on the bike in a large seat bag, and a handlebar bag.

T-Shirt
Shorts - non-riding
Jersey and shorts for day 2
sunscreen
tube
patch kit
tire levers
multi-tool
toothbrush
shampoo & soap
Tissue
Pump
Camelbak or bottles - haven't decided yet

I still have a little room in my bags, and haven't touched my jersey pockets. The weather looks good, so the windbreaker is not going.

Anything else?
